I have been trying to get the Windows 7 bootloader to start Grub with no success. I have installed Gentoo on a new mSATA drive, and have a working Ubuntu installation in my Windows partition (installed with wubi). I would like to keep the Windows bootloader in the MBR.
Here's a description of my system:
Sager NP9170 Notebook
my partitions:
/dev/sda1 750 GB user data (D:) HDD
/dev/sdb1 210 MB System (no windows drive letter) SSD
/dev/sdb2 180 GB Windows (C:)
/dev/sdc1 256 GB Linux (/) mSATA SSD
/dev/sdd1 32 GB flash drive

after installing GRUB to (hd2,0), which should correspond to /dev/sdc1 I used dd to copy the bootloader to a file in my Windows partition, and used bcdedit to add it to the Windows boot menu.
When I try to boot Gentoo I get the following error:

Code:

Grub Geom Error

I have also tried installing GRUB into (hd2) the MBR of /dev/sdc and still haven't gotten it to work.
I have also tried using EasyBCD. With other configurations I have tried I got this error too:

Code:

Grub

It just prints Grub and nothing else.

The only thing that has worked has been to press F7 at boot to select the mSATA drive and load GRUB from its MBR. But then I have to edit the command and change

# grub-install --no-floppy /dev/sdc1
Installation finished. No error reported.
This is the contents of the device map /boot/grub.device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

PS i c, that there is strange error with grub2-probe that tells about "unknown filesystem", but idk how to handle it.

probe is rly buggy, or idk, but it also tells that sda1 & sda3 got an ext2, when it ext4...

btw
Didnt found anything about flag setting in handbook, when "GPT" label selected in "parted".
Somebody should add "set 1 bios_grub on" command, coz now parted with "GPT" case in handbook is incomplete\not working; if somebody choses GPT & knows nothing about it (like me =), when installing gentoo for 1st time he can got an error.
